Script:
What if I told you that someone had developed an energy source that could help us solve our biggest environmental challenges, purify our water and air, make our cities and homes more sanitary, and keep us safe from potential catastrophic climate change? What if I also told you that this energy source was cheap, plentiful, and reliable?
Well, there is such a source. You probably know it as fossil fuel. Oil. Natural gas. Coal.
But wait? Don’t fossil fuels pollute our environment and make our climate unlivable? That, of course, is what we’re told…and what our children are taught. But let’s look at the data. Here’s a graph you’ve probably never seen: the correlation between use of fossil fuels and access to clean water. More fossil fuel. More clean water. Am I saying the more we that we have used fossil fuel, the cleaner our water has become? Yes, that’s exactly what I’m saying.
In the developed world, we take clean water for granted. We turn on a tap and it’s there. But getting it there takes a massive amount of energy. Think of the man-made reservoirs, the purification plants, the network of pipes. In the undeveloped world, it’s a much different story. They lack the energy, so they lack clean water. More fossil fuel. More clean water.
The same is true of sanitation. By the use of cheap, plentiful, and reliable energy from fossil fuels, we have made our environment cleaner. Take a look at this graph. More fossil fuel. Better sanitation.
Okay, what about air quality? Here’s a graph of the air pollution trends in the United States over the last half century based on data from the Environmental Protection Agency. Note the dramatic downward trend in emissions, even though we use more fossil fuel than ever. How was this achieved? Above all, by using anti-pollution technology powered by…fossil fuel: oil, natural gas and coal.
But even without modern pollution control technology, fossil fuel makes our air cleaner. Indoor pollution—caused by burning a fire inside your house, cabin, hut or tent to cook and keep warm—was a deadly global problem until the late 19th century when cheap kerosene, a fossil fuel byproduct, became available in America and Europe. Indoor pollution is still a major issue in the developing world today. The best solution? Fossil fuel.
And now we come to the biggest fossil fuel concern of all—global warming. On this very sensitive topic we need to get our terms straight: There is a big difference between mild global warming and catastrophic global warming. We can all agree on that, right? The issue isn’t: does burning fossil fuel have some warming impact? It does. The issue is: is the climate warming dangerously fast?
In 1986NASA climate scientist James Hansen—one of the world’s most prominent critics of the use of fossil fuels—predicted that “if current trends are unchanged,” temperatures would rise 2 to 4 degrees in the first decade of the 2000s. But as you can see from this graph, since 2000 the trend line is essentially flat—little or no warming in the last 15 years. That’s probably why we hear much less talk about “global warming” and much more talk about “climate change.”

It takes a lot of fuel to heat our homes, preserve our food, and power our gadgets. And for 40 percent of the world, cheap, plentiful coal gets the job done. But coal also releases pollutants into the air, causing environmental damage like acid rain and serious health problems. Can we create a cleaner version of coal? Emma Bryce details the three ways we might strip coal of its foul forces.

Clean coal

Clean coal is a concept for processes or approaches that mitigate emissions of carbon dioxide (CO2) and other greenhouse gases that arise from the utilization of coal, mainly for electrical power generation, using clean coal technology. Currently, the term clean coal is used in the coal industry primarily in reference to carbon capture and storage, which pumps and stores CO2 emissions underground, and plants using integrated gasification combined cycle (IGCC). IGCC involves coal gasification, which provides a basis for increased efficiency and lower cost in capturing CO2 emissions. Prior to the current focus on carbon capture and storage, the term clean coal had been used to refer to technologies for reducing emissions of NOx, sulfur, and heavy metals from coal combustion.

Throughout history, coal has been used as an energy resource, primarily burned for the production of electricity and/or heat, and is also used for industrial purposes, such as refining metals. A fossil fuel, coal forms when dead plant matter is converted into peat, which in turn is converted into lignite, then sub-bituminous coal, after that bituminous coal, and lastly anthracite. This involves biological and geological processes that take place over a long period. The United States Energy Information Administration estimates coal reserves at 7011948000000000000♠948×109short tons (860 Gt). One estimate for resources is 18,000 Gt.

Energy

In physics, energy is a property of objects which can be transferred to other objects or converted into different forms, but cannot be created or destroyed. The "ability of a system to perform work" is a common description, but it is difficult to give one single comprehensive definition of energy because of its many forms. For instance, in SI units, energy is measured in joules, and one joule is defined "mechanically", being the energy transferred to an object by the mechanical work of moving it a distance of 1 metre against a force of 1 newton. However, there are many other definitions of energy, depending on the context, such as thermal energy, radiant energy, electromagnetic, nuclear, etc., where definitions are derived that are the most convenient.

Why Clean Coal Is A Myth

Coal is cheap, efficient, and plentiful-- but horrible for the environment. What about clean coal? Does clean coal exist?

Script:
What if I told you that someone had developed an energy source that could help us solve our biggest environmental challenges, purify our water and air, make our cities and homes more sanitary, and keep us safe from potential catastrophic climate change? What if I also told you that this energy source was cheap, plentiful, and reliable?
Well, there is such a source. You probably know it as fossil fuel. Oil. Natural gas. Coal.
But wait? Don’t fossil fuels pollute our environment and make our climate unlivable? That, of course, is what we’re told…and what our children are taught. But let’s look at the data. Here’s a graph you’ve probably never seen: the correlation between use of fossil fuels and access to clean water. More fossil fuel. More clean water. Am I saying the more we that we have used fossil fuel, the cleaner our water has become? Yes, that’s exactly what I’m saying.
In the developed world, we take clean water for granted. We turn on a tap and it’s there. But getting it there takes a massive amount of energy. Think of the man-made reservoirs, the purification plants, the network of pipes. In the undeveloped world, it’s a much different story. They lack the energy, so they lack clean water. More fossil fuel. More clean water.
The same is true of sanitation. By the use of cheap, plentiful, and reliable energy from fossil fuels, we have made our environment cleaner. Take a look at this graph. More fossil fuel. Better sanitation.
Okay, what about air quality? Here’s a graph of the air pollution trends in the United States over the last half century based on data from the Environmental Protection Agency. Note the dramatic downward trend in emissions, even though we use more fossil fuel than ever. How was this achieved? Above all, by using anti-pollution technology powered by…fossil fuel: oil, natural gas and coal.
But even without modern pollution control technology, fossil fuel makes our air cleaner. Indoor pollution—caused by burning a fire inside your house, cabin, hut or tent to cook and keep warm—was a deadly global problem until the late 19th century when cheap kerosene, a fossil fuel byproduct, became available in America and Europe. Indoor pollution is still a major issue in the developing world today. The best solution? Fossil fuel.
And now we come to the biggest fossil fuel concern of all—global warming. On this very sensitive topic we need to get our terms straight: There is a big difference between mild global warming and catastrophic global warming. We can all agree on that, right? The issue isn’t: does burning fossil fuel have some warming impact? It does. The issue is: is the climate warming dangerously fast?
In 1986NASA climate scientist James Hansen—one of the world’s most prominent critics of the use of fossil fuels—predicted that “if current trends are unchanged,” temperatures would rise 2 to 4 degrees in the first decade of the 2000s. But as you can see from this graph, since 2000 the trend line is essentially flat—little or no warming in the last 15 years. That’s probably why we hear much less talk about “global warming” and much more talk about “climate change.”

It takes a lot of fuel to heat our homes, preserve our food, and power our gadgets. And for 40 percent of the world, cheap, plentiful coal gets the job done. But coal also releases pollutants into the air, causing environmental damage like acid rain and serious health problems. Can we create a cleaner version of coal? Emma Bryce details the three ways we might strip coal of its foul forces.

The Coal vs Clean Energy Show

http://beyondcoal.org Coal has good reason to be so angry, desperate, and increasingly belligerent: He's the nation's oldest and dirtiest energy source, and now he's becoming obsolete as cleaner alternatives come online. -
Founded by legendary conservationist John Muir in 1892, the Sierra Club is now the nation's largest and most influential grassroots environmental organization -- with more than two million members and supporters. Our successes range from protecting millions of acres of wilderness to helping pass the Clean Air Act, Clean Water Act, and Endangered Species Act. More recently, we've made history by leading the charge to address climate disruption by moving away from the dirty fossil fuels and toward a clean energy economy.

What if I told you that someone had developed an energy source that could help us solve our biggest environmental challenges, purify our water and air, make our cities and homes more sanitary, and keep us safe from potential catastrophic climate change? What if I also told you that this energy source was cheap, plentiful, and reliable?
Well, there is such a source. You probably know it as fossil fuel. Oil. Natural gas. Coal.
But wait? Don’t fossil fuels pollute our environment and make our climate unlivable? That, of course, is what we’re told…and what our children are taught. But let’s look at the data. Here’s a graph you’ve probably never seen: the correlation between use of fossil fuels and access to clean water. More fossil fuel. More clean water. Am I saying the more we that we have used fossil fuel, the cleaner our water has become? Yes, that’s exactly what I’m saying.
In the developed world, we take clean water for granted. We turn on a tap and it’s there. But getting it there takes a massive amount of energy. Think of the man-made reservoirs, the purification plants, the network of pipes. In the undeveloped world, it’s a much different story. They lack the energy, so they lack clean water. More fossil fuel. More clean water.
The same is true of sanitation. By the use of cheap, plentiful, and reliable energy from fossil fuels, we have made our environment cleaner. Take a look at this graph. More fossil fuel. Better sanitation.
Okay, what about air quality? Here’s a graph of the air pollution trends in the United States over the last half century based on data from the Environmental Protection Agency. Note the dramatic downward trend in emissions, even though we use more fossil fuel than ever. How was this achieved? Above all, by using anti-pollution technology powered by…fossil fuel: oil, natural gas and coal.
But even without modern pollution control technology, fossil fuel makes our air cleaner. Indoor pollution—caused by burning a fire inside your house, cabin, hut or tent to cook and keep warm—was a deadly global problem until the late 19th century when cheap kerosene, a fossil fuel byproduct, became available in America and Europe. Indoor pollution is still a major issue in the developing world today. The best solution? Fossil fuel.
And now we come to the biggest fossil fuel concern of all—global warming. On this very sensitive topic we need to get our terms straight: There is a big difference between mild global warming and catastrophic global warming. We can all agree on that, right? The issue isn’t: does burning fossil fuel have some warming impact? It does. The issue is: is the climate warming dangerously fast?
In 1986NASA climate scientist James Hansen—one of the world’s most prominent critics of the use of fossil fuels—predicted that “if current trends are unchanged,” temperatures would rise 2 to 4 degrees in the first decade of the 2000s. But as you can see from this graph, since 2000 the trend line is essentially flat—little or no warming in the last 15 years. That’s probably why we hear much less talk about “global warming” and much more talk about “climate change.”

It takes a lot of fuel to heat our homes, preserve our food, and power our gadgets. And for 40 percent of the world, cheap, plentiful coal gets the job done. But coal also releases pollutants into the air, causing environmental damage like acid rain and serious health problems. Can we create a cleaner version of coal? Emma Bryce details the three ways we might strip coal of its foul forces.

"Such arguments are the basis of a new PR campaign launched by Peabody, the world's largest private coal company (which unlike some rivals is profitable, thanks to its low-cost Australian mines). And coal would indeed be a boon, were it not for one small problem: it is devastatingly dirty."
Polluted air causes 5.5 million deaths a year new research says
http://www.bbc.com/news/science-environment-35568249
"Most of these deaths are occurring in the rapidly developing economies of China and India. The main culprit is the emission of small particles from power plants, factories, vehicle exhausts and from the burning of coal and wood."
China May Not FindEnough Coal to Burn
https://www.scientificamerican.com/article/china-may-not-find-enough-coal-to-burn/
"Energy-guzzling China is facing a coal conundrum. Rapid urbanization and industrialization will keep China's coal consumption at record highs of around 4 billion tons per year by 2015. At the same time, the country will have to fight for coal security and to keep its supply line uninterrupted, according to the first energy outlook report from China's EnergyResearch Institute (ERI)."

Clean Coal - Behind the News

The future of coal has been questioned with some people arguing that we should be burning more coal while others say we should be trying to use less of it for environmental reasons. But the PM says 'clean coal' could be the solution to both issues.

"Students will develop a deeper understanding of what is meant by 'clean coal' and the use of coal as an energy source. They will also look at renewable energy sources and their advantages and disadvantages."

Script:
What if I told you that someone had developed an energy source that could help us solve our biggest environmental challenges, purify our water and air, make our cities and homes more sanitary, and keep us safe from potential catastrophic climate change? What if I also told you that this energy source was cheap, plentiful, and reliable?
Well, there is such a source. You probably know it as fossil fuel. Oil. Natural gas. Coal.
But wait? Don’t fossil fuels pollute our environment and make our climate unlivable? That, of course, is what we’re told…and what our children are taught. But let’s look at the data. Here’s a graph you’ve probably never seen: the correlation between use of fossil fuels and access to clean water. More fossil fuel. More clean water. Am I saying the more we that we have used fossil fuel, the cleaner our water has become? Yes, that’s exactly what I’m saying.
In the developed world, we take clean water for granted. We turn on a tap and it’s there. But getting it there takes a massive amount of energy. Think of the man-made reservoirs, the purification plants, the network of pipes. In the undeveloped world, it’s a much different story. They lack the energy, so they lack clean water. More fossil fuel. More clean water.
The same is true of sanitation. By the use of cheap, plentiful, and reliable energy from fossil fuels, we have made our environment cleaner. Take a look at this graph. More fossil fuel. Better sanitation.
Okay, what about air quality? Here’s a graph of the air pollution trends in the United States over the last half century based on data from the Environmental Protection Agency. Note the dramatic downward trend in emissions, even though we use more fossil fuel than ever. How was this achieved? Above all, by using anti-pollution technology powered by…fossil fuel: oil, natural gas and coal.
But even without modern pollution control technology, fossil fuel makes our air cleaner. Indoor pollution—caused by burning a fire inside your house, cabin, hut or tent to cook and keep warm—was a deadly global problem until the late 19th century when cheap kerosene, a fossil fuel byproduct, became available in America and Europe. Indoor pollution is still a major issue in the developing world today. The best solution? Fossil fuel.
And now we come to the biggest fossil fuel concern of all—global warming. On this very sensitive topic we need to get our terms straight: There is a big difference between mild global warming and catastrophic global warming. We can all agree on that, right? The issue isn’t: does burning fossil fuel have some warming impact? It does. The issue is: is the climate warming dangerously fast?
In 1986NASA climate scientist James Hansen—one of the world’s most prominent critics of the use of fossil fuels—predicted that “if current trends are unchanged,” temperatures would rise 2 to 4 degrees in the first decade of the 2000s. But as you can see from this graph, since 2000 the trend line is essentially flat—little or no warming in the last 15 years. That’s probably why we hear much less talk about “global warming” and much more talk about “climate change.”

How to create cleaner coal - Emma Bryce

View full lesson here: http://ed.ted.com/lessons/how-to-create-cleaner-coal-emma-bryce
It takes a lot of fuel to heat our homes, preserve our food, and power our gadgets. And for 40 percent of the world, cheap, plentiful coal gets the job done. But coal also releases pollutants into the air, causing environmental damage like acid rain and serious health problems. Can we create a cleaner version of coal? Emma Bryce details the three ways we might strip coal of its foul forces.

The Coal vs Clean Energy Show

http://beyondcoal.org Coal has good reason to be so angry, desperate, and increasingly belligerent: He's the nation's oldest and dirtiest energy source, and now he's becoming obsolete as cleaner alternatives come online. -
Founded by legendary conservationist John Muir in 1892, the Sierra Club is now the nation's largest and most influential grassroots environmental organization -- with more than two million members and supporters. Our successes range from protecting millions of acres of wilderness to helping pass the Clean Air Act, Clean Water Act, and Endangered Species Act. More recently, we've made history by leading the charge to address climate disruption by moving away from the dirty fossil fuels and toward a clean energy economy.
